Psychoacoustic Evaluation of Listener Localization Accuracy for Broadband and Conventional Reversing Alarms

• Description:
  Two psychoacoustic tests were assessed to determine if the location and direction of vehicle-mounted alerting devices having broadband noise characteristics could be more accurately localized than those having a harmonic frequency spectrum. Reversing conditions were simulated by moving sample backup alarms on a linear sliding platform at a specified velocity. The tests moved the alarms at "direct hit" or "near miss" trajectories toward a KEMAR Manikin, with recordings repeated at 50 azimuthal increments. Participants listened to trajectories over headphones and selected the closest match from depictions of all possible trajectories. The tests revealed little or no substantive improvement in localization acuity for the alarm emitting a broadband noise signal. [Description provided by NIOSH]
